The maximum resolution of the display indicates the number of colour points (pixels) on the computer screen. The higher the resolution the better quality (more detailed) image. For example, 1366x768px means that your computer has 1366 points horizontally x 768 points vertically. High resolution provides more information on the screen and this is directly related to the size of the screen. Nowadays even a 12.1 inches screen can have 1024x768 resolution. At the first glance it looks that this resolution is too high for this size of the screen, however, high resolution provides more comfort.

WVGA (800x480) is characteristic for old portable computers and mini tablet computers of the new generation. WSVGA – ultra mobile portable computers with the display of 10.1’’ (the resolution of 1024x600 can be seen more often).

WXGA (1280x800) – this resolution is mainly characteristic of 12.1’’, 13.3’’, 14.1’’ screen with the relation of sides of 16:9.

HD 1366x768 and 1600x900 is a widespread resolution for the budget and middle class portable computers.

Full HD (1920x1200) resolution combined with high capacity video cards (NVidia Quadro FX vai ATI FireGL) is intended for the professional level 3D modelling work.

WUXGA (1920x1200) – ultra extended graphical arrangement (screen16:10) is intended for watching HD TV.

Attention has to be paid also to the contrast and brightness of the screen. The screen must have the maximum brightness for using the portable computer even in very bright lighting conditions.

AnSSD, or Solid State Drive, is a modern storage device that, unlike hard disk drives (HDDs), has no moving parts and stores all information on NAND memory chips. This is why SSDs are much more reliable, as they can withstand shock, vibrations and temperature changes much better. The main advantage is the high data transfer speeds as well as the lowaccess time. Currently, SSDs equipped with a SATA 3 port deliver data transfer speeds of 500 MB/s on average. However, some drives using M.2 or PCI-Express ports have data throughputs

2000 MB/s.

The battery time indicates the approximate time how long your portable computer will be able to operate after it has been disconnected from the electricity supply when the battery is fully charged.

The battery time depends on the configuration, performed operations and other factors. This indicator usually is based upon the testing results. The lithium batteries built-in modern portable computers usually provide the operation time of 3 to 5 hours and this time depends on the use and configuration of the computer. The maximum battery capacity reduces the time of use of the portable computer. Currently lithium batteries are used in computers and they replaced nickel batteries. It has to be taken into account that the lifetime of portable computer batteries is limited. The capacity decreases with time and it is necessary to replace the battery.

*The battery time may decrease depending on the loading of the portable computer during the time when the battery is used as the power supply to the computer.
